2.3 Hydraulic Diagram
Under normal working conditions, manual change valve
3 stays at position 1, oil from bump flows to the lower
chamber of master cylinder through check valve 8 and
change valve 3 to move the piston. The force of the
piston causes the oil in the upper chamber of the
master cylinder will flow to the lower chamber of slave
cylinder, driving the piston of slave cylinder. The flow
of oil from check valve 8 to the lower chamber of the
slave cylinder is blocked by change valve 3.
To fill oil to or bleed air from slave cylinder, switch
change valve to position 2, then oil from pump flows to
the lower chamber of slave cylinder through check valve
8 and change valve 3, forcing piston up. The flow of
oil from check valve 8 to the lower chamber of master
cylinder will be cut off by change valve 3. If too much
oil is added to the slave cylinder, press the DOWN
button to discharge. When the operation of charging
or discharging operation is completed, switch change
valve 3 back to position 1. For emergency lowering the
scissor lift if the hydraulic or electrical system have
problems, first use the jack to disengage and release
the safety lock plate and then open the emergency
lowering valve(11) to lower the lift slowly and carefully

3 Operation
3.1 Preparatory Inspections
Check for the synchronized and steady
movement of the platforms.
Check the sensibility and reliability of safety
ratchet.
Make sure the platforms would automatically
stop when they reach the max lifting height
(2000mm/79inches)
Check for possible leakage in the cylinder,
hoses and fittings.
Check for possible air leakage in the solenoid
valve, cylinder, pressure regulator valve and
fittings.
Check for any abnormal action and sound in
pump and motor.
Check if the Emergency Stop button works
properly.
3.2 Operational Procedures
Keep speed below 5km/h when driving on the
platforms.
Stop the vehicle when the platforms are
between its front and rear wheels.
Place rubber pads on the platforms where the
lifting points will contact and press UP button to
lift the vehicle to 20cm~30cm (9 to 12 inches)
from the floor.
Make sure that the two platforms are leveled
and nothing unusual is found.
Keep pressing UP button until the vehicle rises
to the required height.
Press LOCK button to lower the lift and engage
the safety ratchet so that the platforms are
leveled with one another.
After the maintenance is done, keep the work
area clear and safe before lowering lift.
3.3 Safety Precautions
The hydraulic overflow valves are well-adjusted
before leaving factory. The manufacturer will
not be responsible for any damage caused by
unauthorized adjustment.
Check the safety lock ratchets are engaged
before going about any under-car jobs.
Place rubber pads on the platforms and spread
them for maximal support.
In case of any leakage in the hydraulic system,
fix the problem and refill the oil to the proper
level.
Caution: Once the safety ratchets are fully in place,
the LOCK button should be released immediately. If
the Lock button is pressed for too long， too much oil
would flow back to cylinder. In this case, the safety
ratchets can not be completely released from locked
position within the set time for the platforms to go up
when the DOWN button is pressed. This can result in
no lowering action, or lowering of only one platform,
which may cause the vehicle to fall from the lift. (Please
refer to the Working Principles of the lift)

4 Troubleshooting
Reasons
Solutions
Fuse is burned.
Voltage is in correct.
Electrical wiring is wrong.
Motor is broken.
Change the fuse.
Supply power of correct voltage.
Fix the wiring.
Change motor.
The motor rotates in the wrong direction.
Oil level is too low.
Height limit switch is stuck or damaged.
Exchange wiring of motor to change
direction.
Add oil.
Repair or replace the height limit switch.
The voltage to the motor is too low.
Pressure of overflow valve is not right.
The lift is overloaded
The hydraulic pump is damaged.
Supply motor with correct voltage.
Adjust the pressure of overflow valve.
Check the weight of the vehicle.
Replace the hydraulic pump.
There is foreign substance in the lowering
solenoid valve.
Lowering restrictive valve is turned too low.
Clean the lowering solenoid valve.
Turn the lowering restrictive valve up.
There is air in upper chamber of Master
Cylinder or Slave Cylinder.
The oil supply can not be cut off because of
the leakage in manual change valve.
Leakage in hydraulic system
Lift Platform 1 close to the max. height,
switch change valve to Position 2 and
press UP Button to add oil. When the
slave cylinder is lifted to max. height,
press Down Button to lower it to the
min. height. Repeat the operation for
three times and adjust the height of
slave cylinder to achieve
synchronization after all the air is bled
from slave cylinder.
Replace manual change valve.
Replace the seal or the cylinder.
The air pressure regulating valve is closed
or too low.
The Solenoid air valve is damaged.
The LOCK button is pressed for too long
time.
Adjust air pressure to 5kg/cm2
Replace the solenoid air valve.
Release the LOCK button immediately
after the safety ratchets are fully
engaged.

5 Maintenance
5.1 Daily Maintenance
Keep the lift clean. Make sure power is cut off
before cleaning the lift.
Keep the working area clean. Excessive dust
in the work area will shorten the lifespan of the
lift.
Before operation, inspect and keep all the safety
devices of lift in order. If any problems are
found, adjust, maintain or replace the parts in a
timely manner.
Make sure that the pits are kept dry and clean.
Inspect if there is leakage in the air valve and if
it is well-lubricated.
5.2 Monthly Maintenance
Refasten the anchor bolts.
Check all the hoses and fittings for possible
wearing and leakage. If any leakage is found
to be caused by worn sealing parts, replace with
parts meeting the specifications.
Check if the roller slide is well-lubricated with
high-quality #2 lithium lubricant.
Apply #2 lithium lubricant on a monthly basis.
5.3 Biannual Maintenance
Check all the moving parts for possible wearing,
interference and damage.
Inspect the lubrication of all the rollers. If the
roller is dragged along in lifting or lowering,
apply lubricant to the roller shaft.
At the end of the first six months, clean the
hydraulic system and replace the hydraulic oil.
Replace the hydraulic oil with N32 hydraulic oil
in winter and N46 in summer.
5.4 Maintenance for 3 Years or
5000 Times Operations
Replace the complex bushings at all joints.
Replace the rollers.
6 Storage and Scrapping
6.1 Storage
When the lift needs to be stored for a long time:
Unplug from power socket.
Lubricate all the parts, including all the contact
surface of the rollers.
Bleed oil from tanks.
Cover the lift with plastic hood.
6.2 Scrapping
When the lift has exceeded its lifespan and can not be
used any more, disconnect it from the electrical supply
and dispose of as required by the local regulations.
